3 Claims.

Our invention relates to a manually operated press in which tobacco,after being stripped from the stalks and hung on sticks, can be pressedinto bales to retain it in a case condition so that it can be easilyhandled.

One object of the invention is to provide a press of this characterwhich is collapsibly constructed so that it can be easily taken down,moved to another location and then quickly set up for further use. Thecollapsible construction also permits the bale to be removed intactinstead of being taken apart one stick at a time, as might be necessaryif the tobacco was pressed in a xed baling chamber.

A further object is to provide a simple and inexpensive tobacco presswhich is free of pawls, ratchets, sprockets, gear wheels, and similarmechanisms the presence of which would add considerably to the cost ofconstruction and maintenance.

Another object is to arrange the working parts in' such manner that thepress can be manually operated by one or two men.

Other objects will hereinafter appear and in order that the inventionmay be readily understood reference will now be had to the accompanyingdrawings, in which:

Fig. 8 is a detail perspective View of one of the standards forming aportion of the frame.

Fig. 9 is a'broken detail of the upper portion on one of the standardswith cable tensioning means mounted thereon.

Fig. 10 is a detail cross sectionv of a portion of the tensioning means.

Fig. 1l is a detail perspective view of one of a plurality ofantifrictional devices employed in carrying out the invention.

In carrying out the invention we provide a baling chamber 2 closed atits bottom portion by a platform 4 fixed upon a pair of horizontal beams6 forming the lower portion of the collapsible frame of the press andresting near their ends upon a pair of sills 8. l

' The baling'chamber 2 is open at `both sides asclearly` Showny by Fig.4, so that it may `be charged from both sides lwith the tobacco A whichis usually supplied in the form of hands B mounted upon sticks C. Thevertical ends of the baling chamber 2 are closed by end walls I0 each ofwhich is xed `to a pair `of standards I2 fixed at their .lower endsVupon the sills 8 and constituting a portion of the frame of the press.The beams 6 are equipped with fixedly mounted angle irons I4 which abutthe sills 8 and hold the same in spaced relation to each other.

The upper portions of the end walls I0 are held in spaced relation toeach other by means of a removable beam I6 which bears at its Aendsagainst the inner surface of said end walls II). The beam I6 is providedat its terminals with angularmetallic straps I8 which engage the upperedges and the outer surfaces of said end walls and coact with the beamI6 in holding the end walls in spaced relation to each other.

The tobacco is compressed to the desired density in the press by meansAof a plunger 20 reciprocably mounted within the baling chamber 2 andincluding a pair of horizontal beams 22 slidably engagingthe standardsI2. The plunger 2] is manually operated by means of a pair of windlasses24, a pair of upper cables 26 and apair of lower cables 28. Thewindlasses may be of any suitable form. In the present instance eachwindlass comprises ahand wheel 39 and a horizontally disposed shaft 32uponone end of which latter the hand wheel 30 is xedly mounted. The

shafts 32 are journaled in bearings 34 fixed upon the beams 22 of theplunger 20, and each shaft 32 is removablyheld in its respective pair ofbearings 34 by Suitable means such as retaining pins 36.

The upper cables 26 cooperate with the respective windlasses 24 inraising the plunger 20, and each cable A26 is attached vat its upperintermediate portion to tensioning means comprising a shaft 38'journaledin bearings 40 secured to the upper endsof the standards I2. The shafts38 maybe rotated forwardly to wind the cables thereon with a wrench orother suitable tool, not shown,v until the cables, 26 have beentensioned to thel desired degree, whereupon said shafts 38 are thensecured from accidental backward rotation by pins 42 inserted throughopenings 44 in the bearings 40 and two of the diametrically opposedopenings 46 in the shafts. The lower end of each cable is spaced apartas shown on Fig. 2 and secured to the respective windlass shaft 32 uponwhich it is adapted to be wound for the purpose of raising the plunger20.

The cables 28 are spread apart at their lower ends and attached toeye-bolts 48 secured to the sills 8. The cables Z8 are attached at theirintermediate portions by eye-bolts 50 to the respective windlass shafts32vupon which they are adapted to be wound for the purpose of pullingthe plunger 20 downwardly upon the tobacco to compress the same. Byspreading the ends of the cables 26 and 28 apart as stated, theycooperate with the shafts 32 and beams 22 in lholding the plunger 20 ina horizontal plane.

The cables 26 and 28 are so attached to the respective shafts 32 thatthe cables 26 unwind as the cables 28 are wound upon said shafts andvice versa. In order to relieve the cables 26 and 28 of the excessivewear to which they would be subjected if permitted to rub against eachother, We interpose antifriction members 52 between said cables to holdthem out of frictional engagement'witl'reachother. The antifrictionmembers 52 are preferably arranged in pairs and loosely mounted upon'therespective'shafts'32 yso that said antifriction members 52 may rotateindependently of eachother and also be moved axially upon the shafts 32by the convolutions of the cables 28 and 28 as they wind and unwind fromthe shafts 32. The'shafts 32 are also equipped with antifriction members54 which prevent the convolutions of the cables 26 from coming intofrictional contact with the standards l2 as the cables 2G are wound uponthe respective shafts 32. The antifriction members 54' are held inspaced relation to the bearings 34 by spacing sleeves 56 loosely mountedupon Athe shafts 32.

After the plunger 20 has been pulled downwardly to compress the 'tobaccoto the desired degree it is held in downward position for'a suitableperiod by detents 58. Each detent 58 is provided at one end with fixedjaws 60 for engagement over one of the spokes of the adjacent hand wheel30,' and is pivotally connected at its other end to a respective bearing62 secured upon the plunger 23. I v l v When it is desired to remove thebale of tobacco from the baling chamber, or remove the press from onelocation to another it may be readily taken down by removing theupperbeam I6 from the end walls I0, after which the retaining pinsv 33are removed from the bearings 34 so that 'the shafts 32 can be rolledupwardly on the cables 26 to clear said bearings.` The standards l 2,with the' end walls l il, are then lowered so that the plunger 29 withits beams 22 can be lifted from the bale, which latter may then beremoved intact from the platform 4. When it is desired toset the pressup for further use lit can bel readily reassembled for that purpose.

For protection of the rcompleted bale itfmay raised and the sticks C arewithdrawn from the hands B. A sheet is then spread over the top of thebale which is again compressed by lowering .the plunger 2U. The ends ofthe two sheets are comprising a platform at the lower end of the balingchamber of the press, two pairs of standards adjacent to the ends ofsaid platform and forming the corners of the balingvchambenkawallfsecured to each pair of standards forl closing theends'of thebaling chamber, a horizontal beam connecting the upper portions of theclosed ends of the baling chamber, a plunger reciprocably mounted in thebaling chamber and including apair of horizontal beams slidably engagingthe standards,A and manually actuated means for operating said plunger.

2. A collapsible baling press comprising a pair of transverse sills, twopairs of standards fixed upon said sills and forming the corners of thebaling chamber of the press,r a wall uniting each pair of standards andclosing'the ends of the baling chamber, a pair of horizontal beamsresting uponv the ysills yand bearing against the standards to assist inholding the latter in upright position, Ya platform forming the bottomof the baling chamberand luniting said beams with which they cooperatein supporting the standards in upright position, a removable upper beambearing against the upper portions of the end walls to cooperatetherewith in supporting the standards in upright position, elementsfixed to'thefends'of said upper beam and removably engaging the upperportions of the end walls, a plunger operably mounted in the balingchamber and including a pair 'of beams slidably engaging the standards,and manually controlled means for operating said plunger. v

3. A tobaccopress comprising a baling case, a plunger reciprocablymounted within said baling case,l a pair of windlasses mounted uponsaidplunger to reciprocate therewith, shafts paralleling the windlasses androtatably mounted at the upper portion of the baling case, cablesattached at both ends to the respectivewindlasses and at theirintermediate portions to the respective shafts, means for rotating theshafts to tension the respective cables, cables attached at both ends tothe lower portion of the baling case and attheir intermediate portionsto the respective windlasses at a point betweenv the ends of themst-mentioned cables, and antifriction'members loosely mounted upon therespective windlasses between the first and last-mentionedA cables toprevent said cables from frictionally engaging each other as they arealternately wound upon and unwound from the windlas'ses to raise andlower the plunger.
